BLOCK OF ICE CYLINDER.

Application filed September 15, 1926,l SerialtNo. 135,675. Renewed November 24, 1928.

This invention is directed to a portable rc'lrigerating device designed particularly for the production of ice in blocks, ice cream, or the cooling ot liquids in an expeditiousand y Figure 2 is a view in elevation, partly in.

section, showing the means for clamping the material container in position tofseal therefrigerant container.

Figure 3Vis a sectional detail illustrating the means for securing the removablecover lor the material container in sealed relation to such container.

The improved refrigerating device comprises a refrigerant container including an outer metallic .vessel 1 within which is secured a double walled glass lining 2 supported at the lower end by a rubber cushion The lining 2 of double walled formation, as stated, may, it desired, be filled witlian insulating material, as tor example mercury f A material container 4, which maybe of metal er glass, is adapted to be inserted into the open upper end oi the refrigerantcontainer, the material container having its verticalY wall 5 upwardly divergent and 'such' container being of a diameter to provide a space 6 between the container and lining of the refrigerant container into which space the chemical refrigerant isV introduced..

The material container 4 has an annular bearing Ward from lthe upper edge of the wall 5, (he outer edge of the bearing section supporting an integral cylindrical upstanding Wall LQ U. container is extended above the lining 2 in the orm et an annular flange 9, the interior diameter of which is slightly 1n excess of that of the vessel 1. A cover 10 isk arrangedto;

tween the upper and lower walls at one end fit over and close the upper end of thel wall 8 and irictionally cooperate at its lower end with the flange 9. *Y

lt is important that when the partsk are section T extended laterally and out-I lhe metallic vessel 1 of the refrigerantA assembled for use that the material container 4 seal the v*upper open end of the refrigerant container, and for this purpose there is provideda gasket 11 having an interior opening to snugly receivev the material con- Vtainer and of a diameter suiiicient to overlie andrest upon the upper end of the lining 2 of the refrigerant container.: yThe bearing section 7 of the material container is formed withv an annular depending projection 12y adapted, when the material container is in place in the ,refrigerant container, to bearl upon the gasket 11 in line with the glass 'lining 2 of the refrigerant container. y

Dow'nward .pressure `is exerted, upon the lmaterial container to cause this projection' to have sealing connection with the gasket through the medium of interconnected levers 13 and 14 arranged on opposite sides of the device, the former having a curved upper end 15 passing loosely through an opening 16 in the cover 10 and engaging in an openvingl? in the upstanding `wall 8 of the material container.

The lower end of this lever 13 is connected at 18 to the linger lever V14, ksuch connection being beyond the pivotal support 19 of such iinger lever, ears 2O projecting in spaced relation from the vessel 1 providing for the pivotal support of the linger `lever at 19,

as shown in Figure 2. Obviously, inv the' movement ofthe vfinger lever, the operating lever 13 is moved vertically to compel similar movement' oi the material container to thus seal'the latter in'position or4 provide for the convenient removal of such container. r

The material container 4 is provided with a closure 21 for sealing the material'receiving space of such container at will. The closure whichv includes-y a portion to fit within the upper end of the wall 5 is also provided with a vertically offset outstanding lateral flange 22 adapted to overlie and rest upon a sealing gasket 23 placed upon the uppersurface of the bearing section 7. Clamping means for the closure yare provided including a bar 24 loosely connected with the cover by straps 25 and adapted to'seat at its ends -in socket pieces 26 carried by and projecting inwardly from-thewall 8 of the material container.

The sockets include upper and lower Walls 27 and anend Wall 28 closing the space beof the socket piece. Theclosing Walls 28 lare arranged'at opposite ends of respective socle llO sockets tothe limit of thev end walls and prevented thereafter from moving in the saine direction. A set-screw 29 has threaded eonl nection with the bar 9 and bearsupon or ina-y' screw may be adjusted to clamp the closure in sealing cooperation with the material' container 4l'. Reverse movement ofthe screw followed by a swinging,Y movement of the bar 24 to reino've the ends from the sockets pei inlits bodily sei'iaration of the closure froin the container, though of course the container with the closure in sealed position may be readily removed as an entirety frein the refrigerant container. j y

If desired', a handle ineinber or handle ineinbers@ may be connected to the cover l() for conveniently handling` the device as a whole. f

In the use of the device, the refrigerant chemicals are introduced'into the refrigerant container, following' which the material container with the inaterial to be cooled or frozen is introduced into such refriperai'it. The closure 2l is applied and sealed in position, the cap or cover l0 .is then applied, the operating levers 13 passed through the openings 16 in the cap and fitted into the penings l? in the material container wall, and the finger levers 14 are turned downwardly to cause `a sealing` cooperation between the material container and the refrigerant container.

What I claim as new is:

l. A refrigerating device including a refrigerant container, a inaterial vcontainer vadapted to l e seated in the refrigerant container in spaced relation thereto, said inaterial container extending` above the refrigerant container and provided with an out wardly extending; flange and an upstandiitg wall, a si-ialii'ig` gasket carried by the refrigerant container and adapted to be engaged b the outwardly extending flange of the material container, a closure for' the container which overlies the outwardly vextending connection with the opstanding wall, and aA screw between the bar and closure to clainp the latter to the material container, and means carried by the refrigerant container to engage the upstanding` wall of the material container above the refrigerant container to clamp the material container in sealing cooperation with the refrigerant Container.

2. A refrigerating` lined vessel to receive the refrigerant, a. container to receive the material to be treated, said container having` a bearing portion to overlie the upper end of the vessel and a wall extendingabove the bearing portion, a ,gasket between said bearing port-ion and the vessel, a

de 1ice comprising a' cover fitting over the upstanding wall of the 1 material container and the upper end of the vessel, levers supported by the vessel and adapted to pass through openings forined in the cover and enjcgaggesaid upstandingwall of the container to force the bearine portion into y scalingv cooperation with the gasket, a closure for the container, and ineans for sealing` the closure in place.

3. A refrigerating device comprising a lined vessel to receive the refrigerant, a container to receive the material tobe treated, said container having` a bearing' port-ien to overlie the upper end of the vessel and a wall extending above the bearing portion, a gasket between said bearing; portion and the vessel, levers supported by the vessel and adapted to engage said upstanding wall of the container to force the bearing` portion into sealing; cooperation with the gasket, a closure for the container, a bar carried by the closure, sockets carried by the upstanding wall of the container to receive the end of the bar, and a setscrew inserted through the bar and exerting endwise pressure upon the closure.
